California has the strictest worker classification rules in the country. Most states use a multi-factor balancing test to determine whether a worker is an employee or an independent contractor. California uses the ABC test, which presumes every worker is an employee and places the burden on the hiring business to prove otherwise. That reversal matters enormously: in most states, misclassification is an oversight that gets corrected. In California, it is presumptively a violation that requires the business to affirmatively disprove.
The consequences of getting this wrong in California range from owing unpaid wages and benefits to facing penalties under the Labor Code, liability for payroll taxes, and exposure to class action lawsuits. Understanding how California's rules actually work is the starting point for any business that hires workers in the state.
The ABC test: California's default classification standard
California's ABC test, codified in Labor Code Section 2775 and established through the 2018 Supreme Court decision Dynamex Operations West v. Superior Court, requires a hiring entity to satisfy all three prongs to classify a worker as an independent contractor. Failing any single prong means the worker is an employee under California law.
Prong A requires that the worker is free from the control and direction of the hiring entity in connection with the performance of the work, both under the contract and in fact. This goes beyond what the contract says. A business that claims a worker is independent but dictates their hours, requires them to work on-site, or supervises their methods closely will fail this prong regardless of what the agreement provides.
Prong B requires that the worker performs work that is outside the usual course of the hiring entity's business. This is the most frequently dispositive prong and the one that catches many businesses off guard. A bakery that hires a freelance baker to help during the holiday rush cannot classify that baker as a contractor under California law, because baking is the usual course of the bakery's business. A bakery that hires a freelance graphic designer for a marketing project can, because graphic design is outside the usual course of the business.
Prong C requires that the worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed. A worker who only does this type of work for one company, has no other clients, and has no independent business presence will struggle to satisfy this prong.
AB 5 and the codification of the ABC test
California Assembly Bill 5, which took effect January 1, 2020, codified the ABC test from Dynamex and extended it beyond wage claims to the full range of California employment laws: workers' compensation, unemployment insurance, paid sick leave, and more. AB 5 also added specific industry exemptions that Congress had been lobbying for since the Dynamex decision.
AB 5 was subsequently amended by AB 2257 in 2020, which expanded the exemptions significantly. The current exemptions cover a substantial number of professions and industries, but they are narrow and specific. Meeting an exemption does not automatically classify the worker as an independent contractor; it means a different classification test applies instead of the ABC test, typically the older Borello multi-factor test, which is easier to satisfy but still requires genuine independence.
Key AB 5 exemptions
The exemptions under AB 5 and AB 2257 cover a wide range of occupations, but each comes with its own conditions. The most significant include:
Licensed professionals including doctors, dentists, lawyers, architects, engineers, accountants, and certain other licensed occupations are exempt from the ABC test when they meet specific conditions, including maintaining their own business location, setting their own rates, and having the ability to work for other clients.
Business-to-business contractors are exempt when a genuinely independent business entity (not an individual) contracts with another business to provide services, as long as the contracting business meets a 12-factor test including maintaining its own business license, having its own equipment, and not being economically dependent on the hiring entity.
Referral agency workers, including those who work through platforms connecting clients with service providers for tasks like cleaning, tutoring, and pet care, are exempt under specific conditions.
The entertainment industry has specific carve-outs for writers, directors, producers, and other creative roles under detailed conditions. Freelance journalists and photographers are also covered under specific conditions that generated significant controversy when AB 5 was originally passed.
Notably absent from the exemptions: gig economy drivers. Proposition 22, passed by California voters in November 2020, created a separate classification for app-based transportation and delivery workers, though its constitutionality has been contested in courts. As of 2026, Proposition 22 remains in effect following a California Supreme Court ruling upholding it in July 2024.
The Borello test: what applies when an exemption is met
When a worker qualifies for an AB 5 exemption, California applies the older S.G. Borello & Sons v. Department of Industrial Relations multi-factor test. Borello looks at the totality of the relationship rather than requiring all three ABC prongs to be satisfied. Factors include the right to control the work, the worker's opportunity for profit or loss, the permanency of the relationship, whether the work is part of the regular business of the hiring entity, the worker's investment in equipment or facilities, and whether the service requires special skill.
Borello is more flexible than the ABC test, but it is not a rubber stamp. California courts have found employee status under Borello even where businesses believed they had a legitimate contractor relationship. The key question under Borello, as under the ABC test, is the degree of control the business actually exercises over how the work is performed.
Consequences of misclassification in California
The exposure from misclassifying employees as contractors in California is substantial and runs in multiple directions. The California Labor Commissioner can assess back wages for minimum wage violations, unpaid overtime, missed meal and rest breaks, and unreimbursed business expenses, all of which employees are entitled to but contractors are not. Waiting time penalties for unpaid final wages can add up to 30 days of wages per affected worker.
The Employment Development Department can assess unpaid payroll taxes, unemployment insurance contributions, and state disability insurance contributions for the entire period of misclassification. The IRS can similarly assess federal payroll taxes and penalties.
California's Private Attorneys General Act (PAGA) allows workers to sue on behalf of themselves and other aggrieved employees to recover civil penalties for Labor Code violations. PAGA claims do not require class certification, making them significantly easier to bring than class actions. A single misclassified worker who discovers the issue can trigger a PAGA lawsuit covering all similarly situated workers, with penalties running per violation per pay period.
Workers' compensation exposure is particularly acute: if a contractor is injured on the job and a court later determines they were actually an employee, the business may face workers' compensation liability it did not insure for.
A real-world example
A San Francisco software company hires a developer as an independent contractor to work on a year-long project. The developer works 40 hours per week, exclusively for this company, uses the company's equipment, attends daily standups, and is supervised by a product manager who reviews and approves the developer's work. The company pays the developer a flat monthly rate with no other clients involved. Under the ABC test, the company fails Prong A (control and direction), likely fails Prong B (software development is the core of the company's business), and fails Prong C (the developer has no independent business). The developer is an employee under California law regardless of what the contract says. The company owes back overtime, missed break premiums, and expense reimbursements, and faces potential PAGA liability for every pay period of misclassification.
What businesses should do
Any business with workers in California should audit its contractor relationships against the ABC test before a dispute arises. The audit should focus on Prong B first, since it is the most commonly dispositive: if the work being done is within the usual course of the business's operations, the ABC test almost certainly requires employee classification regardless of how the other factors look.
For workers who cannot be classified as contractors under the ABC test, California offers no workaround through contract language. The classification follows the economic reality of the relationship, not what the parties agree to call it. Businesses that cannot satisfy the ABC test have two options: reclassify the workers as employees, or restructure the work arrangement so that the worker genuinely operates an independent business that provides services to multiple clients.
For independent contractors who believe they may have been misclassified, the California Labor Commissioner's office handles claims, and the statute of limitations for wage claims in California is generally three years. LawDepot's Independent Contractor Agreement can help structure a genuine contractor relationship with clear terms on scope, payment, and independence, though no contract language overrides the ABC test if the economic reality points to employment.
Frequently Asked Questions
Does the ABC test apply to out-of-state businesses hiring California workers?
Yes. If a worker performs services in California, California's wage and hour laws apply regardless of where the hiring business is located or incorporated. An out-of-state company that hires a California-based remote worker is subject to the ABC test for that worker's classification. Many out-of-state businesses discover this when a California worker files a wage claim or PAGA lawsuit, at which point the full weight of California's classification rules applies retroactively to the entire period of the relationship.
Can a worker choose to be an independent contractor in California?
No. Classification under California law is determined by the economic reality of the relationship, not by mutual agreement. A worker cannot waive their right to be classified as an employee simply by signing an independent contractor agreement. If the ABC test or Borello test indicates employment, the worker is an employee as a matter of law. This is frequently misunderstood by both businesses and workers who believe that a signed contract expressing mutual intent to have a contractor relationship is dispositive. It is not.
How does California's ABC test differ from the federal test?
The federal government uses several different tests depending on the context, including the economic reality test for Fair Labor Standards Act purposes and the common law control test for tax purposes. Neither federal test presumptively classifies workers as employees the way California's ABC test does. The ABC test's Prong B, requiring that the work be outside the usual course of the hiring entity's business, has no equivalent in most federal tests and is the primary reason California's standard is stricter. Businesses that comply with federal classification rules may still be violating California law.
What is the statute of limitations for misclassification claims in California?
The statute of limitations varies by the type of claim. Wage claims under the Labor Code generally have a three-year statute of limitations. PAGA claims must be filed within one year of the alleged violation. Unemployment insurance and payroll tax assessments have their own timelines administered by the EDD. Because different claims have different limitations periods and can be brought simultaneously, the total exposure window for a misclassification relationship can extend back several years from the date a claim is filed.
Does Proposition 22 affect my business if I'm not a rideshare or delivery company?
No. Proposition 22 created a narrow carve-out specifically for app-based transportation network companies and delivery network companies, covering their drivers and couriers. It has no application to other industries. Businesses outside the gig transportation and delivery space remain fully subject to the ABC test under AB 5. Proposition 22's existence does not signal any general softening of California's worker classification rules for other industries.
